To create icons without text in your Chrome browser , simply navigate to your favorite web page, such as http://www.google.com and press ctrl and d at the same time.
You will be greeted with a pop-up window with the name and folder where you can select the location of your bookmark. Leave it set to the Bookmark Bar option and then delete the name out of the name box.
Click done and you're all set.
Try doing this with a few of your favorite websites or create your own folders with your most visited links. It's quick, efficient and it looks pretty sweet too!
